The standard recommendation to prevent allergic reactions is to remove the food allergen from the diet of the person with the food allergy. But one type of treatment, called food oral immunotherapy (OIT), exposes them to small amounts of the food allergen. But before you consider it, it helps to know what it is, how it works, and the risks and benefits.

OIT is a food allergy treatment that retrains your child’s immune system to respond differently to food. It helps the body gradually desensitize (tolerate) a food allergen. It does this by slowly raising the amount of food allergen your child can eat before it triggers an allergic reaction. The only OIT treatment that is FDA approved thus far is for peanut allergy.

You should never try OIT without the help of an allergist. Your child’s allergist carefully plans and supervises the OIT process. If you try it on your own, you will put your child at risk for anaphylaxis, a severe allergic reaction.

Successful treatment of OIT may give your child something called “bite protection.” This means a lower chance of having an allergic reaction if your child accidentally eats a small amount of the food allergen. Some children may even be able to eat the food freely in their diet after reaching the final stage of OIT treatment program.

OIT is not a cure for food allergies. It may not be the right treatment for everyone. It is a process that takes careful thought, time, and commitment. But for many families, it is a valuable treatment that can reduce stress and may improve quality of life. It may allow your child to eat foods with less stress and worry. Talk with your child’s doctor to see if OIT is right for your child.
